Think the love in your heart is unique? You might be right. It turns out that everyone's heart beats to its own rhythm. Scientists think they can take that uniqueness to protect your data. Isn't that lovely?

To prove the point, researchers led by Ching-Kun Chen, an electrical engineer at National Chung Hsing University in Taiwan, have developed an algorithm that turns an electrocardiograph (ECG) reading from your palm into an encryption key.

"He says the goal is to build the system into external hard drives and other devices that can be decrypted and encrypted simply by touching them," reports New Scientist magazine.
